Missouri Orthopaedic Institute Trizou Triathlon has now grown into one of, if not the largest, pool swim triathlons in the nation. It is certainly one of the most popular early-season triathlons in the region. The event features the very popular time trial pool start in that amazing state-of-the-art Mizzou Aquatic Center competition pool. The DuZou Duathlon and SuperSprint were added to introduce the beginner athlete to the world of multi-sport. This is the perfect way to introduce someone to the sport!
